' Application filed December 5, 1893. Serial No. 492,844. (No model.)

To a/ZZ whom it may concern,.-

Be it known that I, CHARLES QUAST, a citizen of the United States,residing at Marion, in the county of Marion and State of Ohio, haveinvented certain new and useful Improvements in Traction-Engines, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

It is the object of my invention to provide a traction engine capable ofbeing readily reversed or driven at dierent speeds without stopping themotor shaft and without requir- The invention includes reversing gearingwith clutches and speeding gearing with clutch mechanism arranged sothat the operator may stop the machine by throwing either clutch to itscentral position.

It includes further compensating gearing whereby one wheel may turnfaster than the other at dierent speeds in turning curves and in variousfeatures of construction hereinafter pointed out.

In the drawingsz-Figure 1, is a side view of the machine; Fig. 2, asectional plan view; Fig. 3, a detail view of one of the clutches, andFig. 4, a sectional elevation.

1 is the drive shaft of the motor driving the traction. Said motor isnot shown but may be of any suitable construction. The shaft 1 carriesspur-gear 2 meshing in spur-gear 4 keyed on shaft 8, which has keyedthereon two clutch shells 7 and 95 and loose bevelgears 185 and 107.Shaft 8 is journaled in bearings 10 and 106, Fig. 2.

In clutch shells 7 and 95 are friction-rings '5 and 96 carried throughjaw-blocks 75 and 97 and guides 80 and 102 on the bevel-gears 185 and107. These bevel gears have hubs 181 which abut midway between the gearsand turn with them loosely on the shaft 8. `On these hubs slide clutchsleeves 83 and 93 which have lugs to carry toggle connections 82 and 94which connect with toggle-levers 76, 79, 98 and 99. Toggle-levers 76 and98 connect on one end with blocks 74 and 186 of clutch-rings 5 and 96and on the other end with lugs of clutch-sleeves 83 and 93. Togglelevers79 and 99, connect at one end with cross pieces 78 and 100 which connectthrough set-up bolts 81 'and 101 with wedge 9 and 103 which fits in theopen cut end of frictionrings 5 and 96, and on the other end theselevers connect with lugs of the clutch-sleeves 83 and 93. Wedges 9 and103 have tails 81 and 104 which slide in the guides 80 and 102 of thebevel-gears 185 andf107. Clutch-sleeves 83 and 93 have a groove 92 whichreceive the rollers 182 of levers 84 and 91, which are pivoted near thecenter in bracket 177 at 86 and 105. The other end of said levers slideby rollers 180 in grooves 87 and 90 of Vclutch cam 89 journaled in thebracket 177. The grooves of said cam are of such nature that one clutchonly is in working position to throw the corresponding clutch ringinengagement with its clutch shell or both are out of working position.The clutch-cam is fastened on shaft 29 journaled at 178 and carrieskeyed on one end spur-gear 30 which meshes in segment 3l. Segment 3l isconnected with lever 33 and is pivoted in bracket 34. Lever 33 connectsthrough rod 36 with lever 73 which is pivoted at 38 and has a large end44 carrying a latch-rod 45 guided in eye 43 and having by link46connection with handle 50. Quadrant 39 has notches 40, 41 and 42, eachone being one position of the clutch-cam and so one po-` sition ofeither lone of the clutches. Bevel gear 185 and107 meshing withbevel-gear 6 keyed on shaft 108 journaled at 11. As both clutch shellsare keyed on vshaft 8, by bring# ing either one of the clutches in gearthe proper bevel-gear will transmit the motion to the bevel-gear 6 andshaft 108 and this may be in either direction, forward and backward orbetter right and left according to which clutch is thrown in. Shaft 108carries on the other end loose bevel-gears 12 and 13 which rotateloosely on' clutch sleeve 117. Shaft 108 is hollow on the end at 112 inwhich cavity is carried coupling bar 113 which carries pin 114 slidingin groove 111 of shaft 108 and this pin fits in sleeve 117. vCouplingbar 113 has on the other end a groove 119 in which fits lever 118pivoted in bracket 120 at 121. Bevel-gears 12 and 13'have clutch-jaws109 and 116 which fit sleeVe-jawslland 115. Shaft 1 IOO are keyed uponshafts 27 and 184, while bevelj gear 128 is loose. Bevel-gear 128 has arunway 131 against which press rollers journaled in bracket 130 as asupport.

Disk 132 is loose on shaft, it also forms a support for bevel' gear 128.Shafts 27 and 184 work in bearings 135,133 and 147, 146 and carry on theends spur-gear pinions 15 and 158 meshing in` drive gears 16 and 157.157 are carried through arms 25 and 156 by traction wheel :ring 17 which`is through arms Drive gears 16 and 18rand 155 suspended around the hub19 andi; 152 which turns on axle 20. Axle 20 is sup-1 ported throughbrackets 141 `and 142 and fasi tened to channels 3 and 150. Saidsupports 141 and 143 and bearings 135 and 146 are-connected together andwith the `channels by. rods 136, 149 and 145, 137 and 28, 144, thismaking a rigged truss and tying all together. l

Channels are connected by piece 26 which has eye 183 for bitching onwagons and the like.

Traction-wheel is made out of two cast rings 17 and `138 kept at theproperdistanceapartl by 4angular cast in rods 23 which are placed ginsuch way that they brace each other `and make twisting impossible.arms 18 `cast in which are .suspended wat `both ends of the hub 19 andwhich brace one another. cap 139 inserted yinhub 19 by pin 140.

Piece 174carries piece 66 which Ball 173 is carried by carries segment 71 inwhich meshes bevel gear58 carrying on one end wormgear 57. 58 and 57 arejournaled on a shaft bearing; in S56 and 59 both bearings carried bybracket g `63. Bracket :55 carries also at 60 pin 62 and this, roller 6lto support `66 `and segment 71. Q

`form 17], on shaft l52 meshes in worm-gear l 57and said shaft 52 isjourna-led at 53 and has a hand-wheel 51 zat the top by which the.engine is steered. Axle 67 has wheels composed `of a-cast iron ring 70in which l.arms 68 a. me ,cast `and hu'b 169 which is held on shaft` bycap collar 168. As the lever 44 is moved for-ward to engage notch 40 thecorrespond` ingcluitch grooved collar 83 or 93 is shoved toward the gearwheel 18`5or 1070i' that side by the clutch cam. Thuscausing the togglelevers of that clutch for instance, 79 and .7 6 are shoved inward into astraight position by rod 82, thus pressing against the bottom of theclutch-ring 5 and 74, Fig. 3,and shoving the wedge 9 against the cheeks179 of the ring 5 and spreading same apart, which causing the ring tocome in strong contact with clutch-frame or shell 7 and as the same`rotates with the shaft 8, the clutch-ring will be set in a rotarymotion thus transmitting the motion through jaws 74 and blocks 75,slides 80 and tail 81 of wedge 9 to bevelgear 185. Bevel-gear 185 meshesin bevel-gear 6 and the latter being keyed on shaft 108 transmits themotion to sleeve 117 which is splined on shaft 108. As lever 44 isshoved in the notch 40 from the center notch 4l the lever 91 and thatclutch-remainswithoutniotion. In taking the lever 44 yback to thecenterfrom 40 the clutch ring 5 and toggles :are brought ou-t o'f action andthe clutch-grooved collar 83 vbrought into the center position wherethere is no iengagement of eitheryone of the clutches. In shoving thelever back ward past the notch 41 into 42 the opposite lever 91andclutch collar 93 4are brought to position va greater distance fromthecenter and thus bring the toggle-1evers `98 and `99 through rod'94`to a straight position. This causes pressure uponthe bottom oftheclutchring 97 and also shoves the wedge103 between the ring-cheeks ofring 96 which causes tsaid ring to spread and be brought in fcontact`with clutch shell95, which rotates with shaft 8 and is lixedthereto.This `causing the :clutch-ring to rotate carrying with it, through jaws186 and `75, and the `sl-ides 102 with tail 104 of `wedge .103, :thebevel-gear 107 rand :this mesh- `ing in beveLgear 6 transmit the motionto shaft 108 yand sleeve 117. As the lever 44 `is brought back to thecenter again `theclutch `is brought out of action and the rgears stop.Only one lcliutch can bein `mesh .at one time or both out, but neverboth 1in. As thesha'ft rotates always in onedirect-ion `andfeitherfoneof the :gear .wheels 185 or 107 `broughtin mo- `tion the `gear 6 `willmove in opposite `motion through which right and left motion isobtained. Bevel-gears 12 and 13are1both loose on `sleeve 117 and shaft108, but haveclutchjaws 109 .and 116 andsleevc 117 has `correspondingjaws 110 Aand 115. Sleeve 117 is splined on shaft l08fand rotateswithsamein the direction of the shaft. `Grears 12 and 13 mesh in gear128 having two setsof teeth 128X and 14 of twodiffereut diameterscausiinfgltwo different speeds of themain gear `128. Lever 163 is rthespeeding lever and carries :a latch 190 and moves on quadrant 165between the notches 164, 191 Vand 19,3. The movement of lever 1 63 is:transmittedthrough lever 196and rod 162 upon levers 161 and 119. Thelatter engages bolt 113 which iscar-ried by shat`t108. Bolt 113hasapin114 slidingin slot 111 of shaft 108 engaging sleeve 117 so 'that`by moving `lever 163 the sleeve will rnovealso. Bylbringing the leverin notch 191 the sleeve 117 and its clutch jaws 116 `will be shoved inwheel 13 and its jaws 116 through which said `gearbe-` IOO comes lockedand rotates with the shaft 108 transmitting the motion to wheel 128. Bybringing the lever back to its center notch the connection between gear13 and shaft 108 will be broken and the wheel 128 stops. Shoving thelever 163 back into notch 193 the sleeve will clutch and couple gear 12and its coupling jaws 109 causingthe gear 128 to turn with differentspeed according to the difference between gear 128X and 14. This`secures two different speeds, any number of gears of different sizesand relations may be usedvand more notches in quadrant 165 may be foundnecessary also the coupling sleeve may have any number of jaws'to coupleany different number of gears. Gear 128 carries centrically bevel-gears122 on pins 123 between ring 124 and hub 126. 122 mesh in bevel-gears125 and 127 on each side and these are keyed on shafts-184 and 27respectively. Shafts 184 and 27 join with their ends in the hub 126 ofwheel128 but loose. -Grear 128 in being loose on the shafts 184 and 27but in connection through gears 122, 125 and127 make up what is called acompensating gear and allow either one of the shafts and drive wheels torotate ahead or faster than the other one this being necessary in makingcurves. From this it will be seen now that the entire machine can bestopped instantly by reversing lever 44 and valso by speeding lever 163.Also can be run either forward or backward through the gearing systemasdescribed, and at different speed'without stopping or changing the speedof the driving motor. Any number of speeding gearscan be used. The mostessential point in the different speeds is to travel in accommodationwith the roads and to be able to pull heavy and slowly by high speed ofthe driving motor and on verypoor roads. The steering is done by a handwheel 51 in front of the traction. Reversing, starting and stopping isdone by merely moving lever 44 and the speeding is done bylever 163while the motor is not disturbed in its motion and at any moment cangive the full power.
